Add basic docstrings to the array API wrapper functions

The docstrings just point back to the functions they wrap for now. More
thought may need to be put into this for the future. Most functions can
actually perhaps inherit the docstring of the function they wrap directly, but
there are some functions that have differences (e.g., different names,
different keyword arguments, fewer keyword arguments, etc.). There's also the
question of how to handle cross-references/see alsos that point to functions
not in the API spec and behavior shown in docstring examples that isn't
required in the spec.
